IMPRovl-:M ENT 1N GANG-PLows.

Specification forming part of Letters Patent No. 26,587, dated December 27, 1859.

To all whom 'it may concern:

Be it known that I, THOMAS S. HEP'rINsTALL, of Mendota, in the State of Illinois, have iuvented a new and useful machine or implement to plow two or morefurrows of land at the same time, and which implements are commonly called gang-plows; and I do hereby decla-re that the :following is a full, clenr, and exact description of the construction and operation of the same, reference being had to the annexed drawings, makin g a part of this specifcation.

Figure l is a perspective view; Fig. 2, lon gitudinal elevation 5 Fig. 3, a transverse section, and Fig. 4 a plan.

v One of the wheels, A, is placed in the front or fore part of the plow, and each of the other two wheels, B B, is placed on one side of the latter part or end of the plow. The front wheel, A, is a easter-wheel placed at the end of an upright shaft, C, fixed on aspindle, S, fastened to two of the beams Q Qof the plow. This upright shaft (l is extended upward above the spindle S, and is joined by themeans hereinafter mentioned to the other two wheels, B B, and the leverpower hereinafter described. The two wheels B B near theend of the plow turn on crank-axles X X, fixed at the lower part of the shafts D D, made firm on and suspended from a movable spindle, E, thatextends across the four beams of the plow and works in boxes Y Y, fixed on the two outside beams,

F, its spindle E, and the hind shafts, D, and

their crank-axles X, areiconnected with each other, and the triangle F and hind shafts, D

D', being fastened to and made firm on the hind i spindleE, the action of the frontwheehlA, l

and the hind wheels, B B,is mutually dependent and regulated bythe action of each other. Part of the upper side `of the `triangle Fis hollow, and it is supported by the side of the triangle which is nearest the end of the plow.

pleasure regulate their depth init.

By means of the regulator I, in whichthe y triangle nieves, and the adjusting-pin, the 1` plows can be fixed at the height or depth that from time to time is required, andthe leverpole H can then be unshipped andI put out of the plownians way and laid ready for use when wanted.

The rollers or wheels K K are placed behind the first and last plows and on a level withthe bottoms of them. These `rollers K K are intended to press against the unplowed ground y and counteract the tendency of the plows to ,r y l work sidewise, and they will give steadiness to the working of the plows and make the work 1 precise, regular, and excellent. i These rollers K' K will enable the landside ofl the plows to be dispensed with,andthe powerwill be saved i il that is required to overcome their friction.

The nature of the inventionconsists of economizing labor, expense, and time in plowing` land. i

What I claim as my invention, and desire to The arrangement of the wheels `A B B, shafts C and D D, spindle E,triangle F, rod G, leverpole H, regulator I, and rollers K K,as described, for the purposes herein set forth.
